To all 'whom t may concern:

-Be it known that I, LUTHER L. KNOX, a citizen of the United States,residing at Avalon, in the y county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement in Water-CooledFloor Structures, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming.part of this specication, in whichi Figure 1 is a plan view partlybroken away of a portion of the iioor structure embodying my invention;

Fig. 2 is a cross section on the line II--II of Fig. 1;

Figs. 3 and 4 are views similar to Fig. 2, bul; showing two dierentmodifications; an

Fig. 5is. a detail view showing the guard or baie for the outlet.

My invention has relation to water-cooled ioors or latforxns for usearound furnaces and the 1ke, and is designed to provide a simple, strongand durable structure of this character which can -be readilymanufactured and placed in position.

The present application is a continuation of my pending application,Serial No. 868,544, filed October 24, 1914.

Referring first to that form of my invention shown in Figs. 1 and 2:

The floor structureshown in Fig. 1 con sists of a plurality ofhollowrectangular units or sections placed side by side with suitablewater-circulating connections 2. The number and shape of these unitswill depend upon the area of the door space to be covered, as well asupon the shape of such space. In the form shown in these igures, eachunit or section consists of an upper oor plate 3 ofrelatively thickmetal and a plurality of bottom plates 4 and 5. The bottom plate 4 hasall its edges turned upwardly, and these upwardly turned edges arewelded to the under side of thefloor plate 3. Each ofthe plates 5 hasthree of its edges turned upwardly and lwelded to said plate. Thesebottom plates with the ioor plate form a plurality of water-containingand circulating chambers, the upturned flanges 6 forming the walls ofsaid chambers and each flange 6, except the outer ones, being common totwo adjacent cham- Fig.. l. These 'flanges not only form spacers whichincrease the strength of the structure, but they also act as circulatingbales.

In order to hold the water in the chambers and prevent too rapidcirculation therethrough, I preferably provide each outlet connectionwith a guard or;J baiie A of angular form, as shown in Figs. 1 and 5,this guard being of a less height than the full,

depth of the chamber, but considerably higher than the level oftheoutlet connection.

In the form of my invention shown in Fig. 3, the floor plate portion ofthe struc- -ture is composed of a plurality of inverted channels 9,placed side by side with abutting ianges 10. The bottoms of the waterspacersll are formed by plates 12, whlch are welded at their edges tothe inner surfaces of the flanges, as indicated at 13.

In that form of my invention 'shown in Fig. 4, the Hoor plate portion ofthe structure is formed in part of the channels 9a similar to thechannels 9. These channels are, however, separated from eachother, andthe oor surface between them is formed lby plates 14, whose longitudinaledges are welded to the channels, as indicated at 15. The bottom of thestructure consists of a continuous sheet metal plate 16, whichl may bewelded to the flanges of the channels, as indicated at 17.

My invention provides a floor structure which can be readilymanufactured and adapted to t any particular shape, since the diiferentsections or units may be made of any desired size and shape, and eachunit may have any desired number of watercontaining chambers. In theform` shown in Figs. 3 and 4, the circulation between adjacent chambersmay be provided by forming` openings through the flanges of the channelsat desired points.

I claim: l Y 1. A water-cooled iioor unit formed of a plurality 0fmembers having horizontal portions in different planes extending acrossone entire dimension thereof, some of said members in one of the planeshaving vertical portions yformed integrally therewith and fused to amember in the other plane to form water-tight ends and sides of theunits as well as water-tight divisions between different parts of theunit, substantially as described.

2. A water cooled floor formed of a plurality of units, each unit havinga plurality of members having a vertical iange and a horizontal portion,the horizontal portions of adjacent members being connected to eachother at the junction of the horizontal portions and the verticalianges, and a top plate connected to the upper ends of the verticalflanges, said vertical flanges formnee/aseo? ing wallsfor watercirculating channels, substantially as described.

l3. A watercooled ioor structure comprising a hollow box-like structure,having Water inlet and outlet connections, and an angular guard orbaiiie placed adjacent to the outlet connection and extending to abovethe outlet connection, substantially as described. v

ln testimony whereof, I have hereunto set my hand.
